ESTIMATION OF DIFFUSION LOSSES WHEN SAMPLING DIESEL AEROSOL: A QUALITY ASSURANCE MEASURE

Citation:

Impact/Purpose:

Alert managers of PM sampling programs to the need for evaluation of particulate loss in sampling lines as a QA measure.

Description:

A fundamental component of the QA work for the assessment of instruments and sampling system performance was the investigation of particle losses in sampling lines. Along the aerosol sample pathway from its source to the collection media or measuring instrument, some nano-size particles are lost to surfaces. The magnitude of these losses were evaluated by chalending the sampling trains with mono-disperse particles in the 10 to 80 nm size range.
